The holiday jazz that defined generations of Peanuts specials is now at the center of a federal courtroom fight in New York.
Lee Mendelson Film Productions, the company behind A Charlie Brown Christmas, filed a copyright lawsuit on May 20, 2026 in Manhattan federal court accusing a video game publisher of recreating Vince Guaraldi’s Peanuts music without permission for a Snoopy title. The complaint targets background cues in the game that Mendelson’s lawyers say were crafted to pair with Peanuts imagery and asks the court to halt further use of the contested music and to award unspecified monetary damages.
According to Reuters, the case, titled Lee Mendelson Film Productions Inc v. MadCow LLC d/b/a GameMill Entertainment, names MadCow LLC as the defendant and points to GameMill’s 2025 title Snoopy & The Great Mystery Club as the vehicle for the disputed music. Mendelson’s filing says the publisher licensed Peanuts characters for the game but did not obtain rights to the Vince Guaraldi catalog.
GameMill lists Snoopy & The Great Mystery Club among its recent titles and links the project to retailers and digital storefronts. The publisher promotes the game as an adventure starring Snoopy and other Peanuts characters, which the complaint says was deliberately paired with music that echoes the classic television cues.
The complaint alleges the game’s background music sounds “substantially similar” to Guaraldi songs including “Linus and Lucy” and “Skating,” and says GameMill recreated those cues rather than licensing them. Mendelson is represented by Hillel Parness of Parness Law Firm and Marc Jacobson of the Law Offices of Marc Jacobson, according to the filing, which seeks an unspecified amount of monetary damages. Reuters reports that the suit was filed in the U.S. District Court for the Southern District of New York.
Vince Guaraldi’s Peanuts soundtracks have had a long commercial life and sizable cultural cachet. Lee Mendelson’s materials note that Guaraldi’s scores have sold more than five million copies in the United States and that A Charlie Brown Christmas is a multi-platinum album, a pedigree Mendelson says underscores that the music is distinctive and protectable.
Legal Stakes for Publishers
The dispute turns on copyright law and whether GameMill’s audio cues are close enough to Guaraldi’s recordings and compositions to count as infringement. If the court finds the music was unlawfully recreated, remedies could include monetary damages and an injunction against further use, outcomes that often push publishers toward settlement and licensing talks rather than prolonged litigation.
What Happens Next
The case will move through standard federal procedures: the defendant can file an answer or seek dismissal, followed by discovery. A judge could ultimately rule on liability or encourage the parties to settle. For now, Mendelson’s filing sets up a test of how far game makers can go in evoking a beloved soundtrack without a clear license.
